Just over 1/4 inch thick 8670 steel, brut de forge, toxic green and red g10 liners and some sweet ass scales from @bexar_co_burls . This is 13.5 inches in length and a little heavy. But, i did make it for myself, heavy doesnt bother me and i have larger hands. Such a bad ass knife. I was going to keep this for myself, but if someone makes me a good offer, I'm open. Message me.
